Abstract: Authenticity of a paper document (10) is tested by sensing (40) its transparency and comparing (32) the sequence of representations produced, with a sequence of reference representations read (39) from a record of an earlier-made sensing written (38) on the document (10) in an offset-printed (and therefore non-uniform) magnetic stripe (18). The reference sequence is written on the stripe (18) in the form of an encrypted identifier (156, Figure 4) within a bit string (Figure 4) that is interspersed with framing characters (155) and includes a public encryption key (158) and an error-correction code (162). Each data and control bit of the bit-string format is written as an eight-bit character enabling ready distinction between data and control bits and enhancing error detection and correction of the string when read (39) from the non-­uniform stripe (18); the relative timings and the polarities of peaks of the analogue signal from the magnetic reading head 939) determine the data value ("0" or "1" according to timing interval t or t/2) or the control nature (interval 3t/2) or each read bit. The error-correction code is applied to reduce errors and enable decryption of the recorded identifier using the public key, whereby an appropriate degree of correlation for authenticity confirmation, can be achieved with the fresh transparency output (40).

Abstract: A magnetic recording/playback apparatus in which rotational torque from the drive shaft of a single motor is capable of being transmitted to a cassette loading mechanism and a tape loading mechanism includes a worm secured to the drive shaft and a worm wheel for being meshed freely with the worm, the worm wheel being provided with a toothless portion. The drive shaft is coupled to the cassette loading mechanism via the worm wheel. During operation of the tape loading mechanism by the drive shaft, the toothless portion of the worm wheel is brought into position opposite the worm wheel so that a driving force is no longer applied to the cassette loading mechanism. When a cassette is ejected, the toothless portion of the worm wheel is shifted after a tape loading operation, thereby re-­engaging the worm wheel and worm to actuate the cassette loading mechanism.

Abstract: A method for interconnecting nodes in each of a number of nets. This invention involves generating initial zones for all nets and determining cumulative demand for path spaces needed by these initial zones. The demand is then compared with the supply, and scores are determined for the paths of the initial zones. Re­dundant paths with the worst scores are then gradually deleted until there are no redundant paths. If how­ever, demand for path spaces still exceeds supply, expanded zones are generated in areas where demand exceeds supply and redundant paths are gradually deleted until there are no redundant paths. The paths remaining after deletion from the expanded zones are then used to interconnect the nodes of the nets. The nodes are then interconnected using the remaining paths.

Abstract: A device for distributing signals within a sensor system used for monitoring the presence of a specific analyte in a composition by means of an analyte-­sensitive indicator molecule is disclosed. The sensor includes a signal-­generating component, a single-fiber sensor tip that houses the indicator molecule and a signal-measuring component. In one preferred embodiment, the signal-­generating component generates a first optical signal of a wavelength that is sensitive to the indicator molecule, and a second optical signal of a wavelength that is predictably altered by the indicator molecule. The distribution system includes lengths of optical fiber, a dividing connector, a mixing connector, a transmitting connector and a tip connector. The dividing connector connects at least three intermediate fibers to the signal-generating component to thereby receive intermediate signals. At least one of the intermediate signals corresponds to the wavelength of the first signal and one intermediate signal corresponds to the wavelength of the second signal. The mixing connector connects a mixing fiber to the intermediate fibers to thereby receive the intermediate signals and blend them into a single mixed signal. The transmitting connector connects a transmitting fiber to the mixing fiber to thereby receive a portion of the mixed signal, and connects a comparison fiber to the mixing fiber to transmit a portion of the mixed signal to the signal-measuring component. The tip connector connects the transmitting fiber to the sensor tip fiber to thereby transmit a portion of the mixed signal to the sensor tip, and connects an indicator fiber to the sensor tip to thereby transmit a portion of the resulting indicator signal returned from the sensor tip to the signal-measuring component. The intensity of the intermediate signal corresponding to the first signal is maximized at the dividing connector. The intensity of the intermediate signals corresponding to the wavelength of a first signal are bounded by the necessity of transmitting intermediate signals corresponding to the second signal of adequate intensity such that the intensity of the indicator signal of a wavelength corresponding to the wavelength of the second signal is suitable for monitoring the operation of the distribution system.

Abstract: In a method for sealing off existing waste sites or polluted areas, pipes which are approximately parallel to one another are installed under the waste site or contaminated area and a blade is pulled forward between every two pipes. Adjacently situated, sealing plastic sheets which are sealed by joining along their edges are pulled in between the layers of soil separated by the blade. To make it possible to check that the sealing sheets have been correctly drawn in and the joining of the sheets is leaktight, the blade is pulled forward in each case by approximately a sealing sheet width and the sealing sheet is pulled in through a gap in the blade. An edge of the last sealing sheet pulled in is joined to the free edge of the previous sealing sheet in the gap and a mineral sealing compound is introduced at least on one side of the sealing sheet while the blade is being pulled forward.
